Application filed October 27,1905. Serial No. 284,719.

To all whom it may concern:

Be it known that I, MAUEIoE LAUCHER, a citizen of the United States,residing at J ersey City, in the county of Hudsorrand- State of NewJersey, have invented certain new and useful Improvements in Time ValveMechanisms and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in devices or mechanisms forautomatically operating the valves of gas, water, or other pipes,electrical cut-outs or switches, and similar apparatus.

The object of the invention is to provide a simple, durable,inexpensive, and efficient mechanism of this character by means of whichgas, water, or other fluid may be automatically cut off at apredetermined time or an electric current may be similarly cut off.

With the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved device or mechanism applied to a gas-bracket,.so as to operateits burner-valve or cock. Fig. 2 is a perspective view of the bottom orunder side of the device. Fig. 3 is a perspective view of the cut-offshaft with its attached part; and Fig. 4 is a detail sectionalviewthrough the casing of the alarm-clock, showing the manner in which thestop-pin is adjusted.

Referring to the drawings by numerals, 1 denotes the casing of analarm-clock mechanism which comprises the usual dial 2, having minuteand hour hands coacting therewith, an alarm indicator-dial 3, amainspringwinding key 4, and an alarm-spring-winding key 5. Theremainder of this alarm-clock mechanism is inclosed in the casing 1 andmay be of any suitable form and construction.

The key 5 is secured upon one of the outer ends of a shaft 6, whichextends through the casing 2 and forms the alarm-spring shaft of theclock mechanism. The usual alarmspring 7 has one of its ends fixedwithin the casing, preferably to the sto 8, as shown in Fig. 3, and itsopposite end ed to the shaft 6 adjacent to the usual ratchet-wheel 9.Upon one of the outer ends of the shaft 6 is formed or secured a socket10, which is adapted to engage the key 11, upon a burner-valve 12, asshown in Fig. 1, or the, similar key of an electrical cut-out or switchor any other similar appliance. As shown, this socket 10 consists oftwospaced members, which are adapted to engage the opposite sides of theflat key 11.

The socket may be held in engagement with the key in any suitablemanner. As shown, this is effected by suspendingthe casing 1 from theburner-bracket (shown in Fig. 1) by means of a hanger-rod 13. The latterhas its upper end secured between the two members or half-sections of aclamp 14, which engages the burner-bracket. Its opposite or lower end isscrewed into or otherwise adjustably secured in a bracket 15, providedupon the casing 1.

When the device is used upon an electric cut-off or switch which has akey adapted to be rotated continuously in one direction, I

provide means for limiting the rotation of the shaft 6 when released bythe clock mechanism, so that the switch or cut-off will not be rotatedbeyond a point sufficient to break the electric circuit. As shown, thismeans consists of a stop-pin 16, which is adjustably mounted in the pathof the socket 10. As shown, this stop 16 is in the form of a screw,which slides through the curved slot arranged in the top of the casing 1concentric with the shaft 16 and which may be clamped at any desiredpoint in said slot, as shown in Fig. 4 of the drawings. It will be seenthat this stop-pin will limit the rotary movement of the shaft 6, sothat the socket 10, and hence the key of the electric switch, will beturned just sufliciently to'accomplish the desired resuit.

The construction, use, and advantages of the invention will be readilyunderstood from the foregoing description, taken in connection with theaccompanying drawings. It will be seen that the device-may be quicklyapplied to a valve in a gas-pipe, water-pipe, or the like or to the keyof an electric cut-off or switch, so that the valve or switch will beautomatically operated at a predetermined time, which is controlled byadjusting the handof the dial 3.

While I have shown and described the preferred embodiment of theinvention, it will be understood that I do not wish to be limited to theprecise showing herein set forth, since various changes in the form,proportion, and

the minor details of construction may be resorted to Without departingfrom the principle or sacrificing any of the advantages of theinvention. It will also be understood that the device may be used foroperating valves, cut-offs, and switches of any description.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The herein-described time valve mechanism having the casing providedwith the bracket 15 on one side, the hanger-rod attached to said bracketand provided with a clamp, for the purpose set forth, said casing. beingfurther provided with the curved slot 17, the stop-pin 16 adjustable insaid slot and having means to secure it at any desired adjustment, andthe alarm-spring shaft having its ends projecting from opposite sides ofsaid casing, provided at one end with a key, and having thevalve-engaging socket 10 at the opposite end, substantially asspecified.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

MAURICE LAUGHER.
